Fraction By Weight: 100.0%

Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, low body temperature, ringing in the ears, nausea,
vomiting, stomach pain, headache, drowsiness, symptoms of
drunkenness, visual disturbances, lung congestion, kidney damage,
liver damage, coma LONG TERM EXPOSURE: tingling sensation,
menstrual disorders, infertility, reproductive effects, convulsions
SKIN CONTACT: SHORT TERM EXPOSURE: irritation, blisters LONG TERM
EXPOSURE: rash EYE CONTACT: SHORT TERM EXPOSURE: irritation
(possibly severe), tearing LONG TERM EXPOSURE: blurred vision
INGESTION: SHORT TERM EXPOSURE: digestive disorders, symptoms of
drunkenness, lung congestion, kidney damage, liver damage LONG TERM
EXPOSURE: reproductive effects
Medical Cond Aggravated by Exposure:

First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
If breathing is difficult, oxygen should be administered by
qualified personnel. Get immediate medical attention. SKIN CONTACT:
Wash skin with soap and water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical attention, if
needed. Thoroughly clean and dry contaminated clothing and shoes
before reuse. EYE CONTACT: Flush eyes with plenty of water for at
least 15 minutes. Then get immediate medical attention. INGESTION:
Contact local poison control center or physician immediately. Never
make an unconscious person vomit or drink fluids. When vomiting
occurs, keep head lower than hips to help prevent aspiration. If
person is unconscious, turn head to side. Get medical attention
immediately. NOTE TO PHYSICIAN: For inhalation, consider oxygen.
For ingestion, consider gastric lavage.

Flash Point:81 F (27 C) (CC)
Autoignition Temp:981 F (527 C)
Lower Limits:1.1%
Upper Limits:7.0%
Extinguishing Media:regular dry chemical, carbon dioxide, water,
regular foam Large fires: Use regular foam or flood with fine water
spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Cool containers with water spray until well
after the fire is out. Stay away from the ends of tanks. For fires
in cargo or storage area: Cool containers with water from unmanned
hose holder or monitor nozzles until well after fire is out. If
this is impossible then take the following precautions: Keep
unnecessary people away, isolate hazard area and deny entry. Let
the fire burn. Withdraw immediately in case of rising sound from
venting safety device or any discoloration of tanks due to fire.
For tank, rail car or tank truck: Evacuation radius: 800 meters
(1/2 mile). Water may be ineffective.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
are explosive above flash point. The vapor is heavier than air.
Vapors or gases may ignite at distant ignition sources and flash
back. Electrostatic discharges may be generated by flow or
agitation resulting in ignition or explosion.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
required. Protect from physical damage. Store outside or in a
detached building. Store with flammable liquids. Keep separated
from incompatible substances.
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 900 ppm Any
chemical cartridge respirator with organic vapor cartridge(s). Any
powered, air-purifying respirator with organic vapor cartridge(s).
Any supplied-air respirator. Any self-contained breathing apparatus
with a full facepiece. Escape - Any air-purifying respirator with a
full facepiece and an organic vapor canister. Any appropriate
escape-type, self-contained breathing apparatus. For Unknown
Concentrations or Immediately Dangerous to Life or Health - Any
supplied-air respirator with full facepiece and operated in a
pressure-demand or other positive-pressure mode in combination with
a separate escape supply. Any self-contained breathing apparatus
with a full facepiece.
Ventilation:Provide local exhaust ventilation system. Ventilation
equipment should be explosion-resistant if explosive concentrations
of material are present. Ensure compliance with applicable exposure
limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles. Provide an
emergency eye wash fountain and quick drench shower in the
immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
